Multi-function power meter communication interface dedicated DC-DC high isolation module power supply: WRH series power meter RS485 communication interface dedicated 6KVAC high isolation anti-static DC/DC power module Shunyuan science and technology according to the needs of multi-function power meter manufacturers, successfully developed a Watt-hour meter RS485 communication interface dedicated DC / DC power supply module WRH series. The product is designed in accordance with the relevant provisions of the National Power Industry Standard (DL) DL/T614-2007. The standard (DL) stipulates the technical elements of the power industry in ordering, acceptance, and use of multi-function electric energy meters, and at the same time standardizes function settings. . The DL/T614-2007 standard is suitable for measuring single-phase or three-phase alternating-current electric energy installed multi-function electric energy meters (referred to as electric energy meters) with a reference frequency of 50 Hz (or 60 Hz). The standard (DL) specifies the functions and required technical performance of the multifunctional watt-hour meter. One of them clearly stipulates that the voltage of the external RS232/RS485/RS422 of the watt-hour meter on the power meter communication interface must reach 6 KVAC and the voltage must be 6 KVAC. 8KV antistatic protection function.
The WRH isolated power supply can be fabricated using ceramic substrates and printed resistors. It not only satisfies the 6KVAC high isolation and 8KV antistatic protection requirements specified in the power industry standard (DL) DL/T614-2007, but also has an output self-recovery overload short-circuit protection function. . In order to protect multi-rate electric energy meter, it will not be damaged and the user's personal safety due to the short circuit of the communication line, static electricity generated by the interface, and lightning.
